Calla lily plant named ‘Dozanwisl’

ABSTRACT

‘Dozanwisl’ is a new variety of calla lily plant having pink colored spathes that produces 10-14 inflorescences per 14-16 cm tuber. The flower sterns are about 26-31 cm in height. The leaves are dark green with maculations present and a smooth texture.

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Dozanwisl’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of calla lily, botanically known as Zantedeschia sprengeri and hereinafter referred to by the varietal name ‘Dozanwisl’. ‘Dozanwisl’ is a product of a planned breeding program, which had the objective of creating Zantedeschia hybrids for pot flower production in a wide range of colors with a classic flower shape. The new cultivar is a seedling selected from the crossing of Zantedeschia sprengeri seedling Z050967-865 (female parent, unpatented) with Zantedeschia sprengeri variety ‘New York’ (male parent, U.S. Plant Pat. No. 29,645). ‘Dozanwisl’ was selected in 2013 by the inventor in 't Zand, The Netherlands as one flowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Dozanwisl’ by tissue culture was performed by the inventor in November of 2013 in 't Zand, The Netherlands. Subsequent asexual reproductions by tissue culture at the same location have demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained and reproduced true to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plants at approximately 10 weeks from planting in 14 cm pots in 't Zand, The Netherlands under greenhouse conditions, which approximate those generally used in horticultural practice. Color references are made to The 2001 R.H.S. Colour Chart of The Royal Horticultural Society of London, 4^(th) Edition, except where general color terms of ordinary significance are used.

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to be basic characteristics of ‘Dozanwisl’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

-   -   1. Medium pink colored spathes with a dark throat spot;     -   2. Dark green colored leaves;     -   3. Few leaf maculations present; and     -   4. High inflorescence production.

The new variety is similar to its female parent in the following traits: spathe and stem color, throat spot presence, spathe and spadix length, and lanceolate leaf shape. However, ‘Dozanwisl’ exhibits a broader spathe width and weaker flower curve than its female parent. Further, its female parent does not have leaf maculations present. The new variety is similar to its male parent in the following traits: spathe and stem color, throat spot presence, spathe length, a weak flower curve, lanceolate leaf shape, and the presence of leaf maculations. However, ‘Dozanwisl’ exhibits a broader spathe width, later flowering time, shorter spadix length, and shorter plant height than its male parent.

Further, when compared to calla lily plant named ‘Fangio’ (U.S. Plant Pat. No. 28,196), both varieties exhibit numerous pink colored spathes, but the spathes of ‘Dozanwisl’ are medium pink in color, while the spathes of ‘Fangio’ are light pink and cream in color. Further, leaf maculations are exhibited by both varieties.
